Unit was not cooling at all. Controls on door seemed to be working. pulled unit out from wall and unplugged the unit while inspecting control boards for burnt spots. None found. Plugged unit in and compressor came on and temps started dropping. Could not find any spec sheet under or behind this unit. Suspected this unit may have been stuck in defrost. Does anyone have a service manual, tech data sheet or any suggestions on what I need to tell the customer and what may be the problem. This unit is approx. 14 months old and customer is very frustrated that his expensive refrig has failed so soon. Any help will be greatly appreciated. Thanks, Bill
